Why can't I send mail to "cox.net" addresses?
I can't send email to any of my contacts who have a "cox.net" email address. I get this message from "mailer-daemon@aol.com" Failure notice, "We were unable to deliver your message to the following address: ***@cox.net."
I am able to send to those addresses using another mail service so the problem seems to be aol. PLEASE FIX. Is AOL at war with COX?
